a lactone, said polyester resin being characterized in that 10 to 80 mole % of acid
component is an' alicyclic polycarboxylic acid or anhydride thereof, and 10 to 100
mole % of the carboxyl groups capable of developing a resinous acid value is derived
from a polycarboxylic acid which will show a potentiometric midpoint potential in
a non-aqueous potentiometric titration, and the state being incorporated into the
resin, of -350 mV or more.
The coating composition based on said resinous composition is specifically useful
